Camshaft signal panel angle detection gauge

Abstract

A camshaft signal panel angle detection gauge comprises a supporting base, a compressing mechanism, an angle positioning mechanism and a detecting mechanism. The compressing mechanism is installed on a supporting base and located on the outer side of the angle positioning mechanism. The angle positioning mechanism comprises a top base, a rear support and a front support, wherein the top base, the rear support and the front support are sequentially arranged on the supporting base. An angle positioning pin is installed on the top base. The detecting mechanism comprises a sliding rail, a detecting base and a displacement sensor. The sliding rail is installed on the supporting base. The detecting base is installed on the sliding rail. A detecting shaft is installed in the detecting base. An angle detecting block is installed at one end of the detecting shaft. An angle detecting pin, a reference groove and a reference surface are arranged on the angle detecting block. The displacement sensor is fixedly installed on one side of the detecting base. The displacement sensor makes contact with the reference surface of the angle detecting block. The camshaft signal panel angle detection gauge is simple in structure and easy and convenient to operate, calibration is easy, the detection precision of a camshaft is ensured, and the product percent of pass is improved.

Description

technical field [0001] The invention relates to a check tool used for detecting the angle of a signal disc after press-fitting the signal disc onto the camshaft of an automobile engine, and belongs to the technical field of press-fitting of the signal disc and the camshaft. Background technique [0002] The camshaft is a key part of the car engine. The signal disc on the camshaft plays an important role in the smooth operation of the vehicle engine. The signal disc is pressed onto the camshaft of the car engine. The quality of the press-fit affects the quality of the engine. Safety performance, whether the angle of the signal plate press-fitted to the camshaft is accurate affects the safety performance of the engine. [0003] Since the camshaft requires to ensure that the angle between the trigger surface of the signal plate at one end and the reference hole at the other end must meet the product requirements, since the reference hole and the trigger surface are at both ends...

AI Technical Summary

Problems solved by technology

[0004] Before there is no angle detection fixture, the manufacturer can only take a sampling method, take a small amount of press-fitted camshafts to a three-coordinate measuring instrument or other testing equipment, and measure the positional relationship between the signal plate and the pin hole at both ends , this method has high precision, but the efficiency is extremely low and the cost is high. The key is that it cannot be inspected one by one, only random inspection, which leads to the inability to guarantee the accuracy of camshaft press-fitting
